JEWELRY.

SPECIFICATION forming part of Letters Patent No. 482,483, datedSeptember 13, 1892.

Application filed May 26, 1892. Serial No. 484,408. (No model.)

To all whom it may concern:

Be it known that I, HARRSLLEHR, a citizen of the United States ofAmerica, and a resident of Nos. 203 and 205 Madison street, in the city,county, and State of New York, have invented a new and usefulImprovement in Jewelry, of which the following is a specification.

This invention relates more particularly to finger-rings or similararticles of jewelry in which removable stones or settings are used; andit consists in the means for securing the stone or settin gin place, ashereinafter specified.

In the accompanying drawings, forming a part of this specification,Figure 1 is a top view of a ring and setting embodying my in vention.Fig. 2 is a bottom View of a stone or setting removed from the ring.Fig. 3 is an inner plan view of the ring. Fig. 4c is a section acrossthe end of the stone or setting. Fig. 5 is a central longitudinalsection of the setting and a portion of the ring. Fig. 6 is alongitudinal section, on an enlarged scale, of a metal plate and latchemployed; and Fig. 7 is an inner plan View thereof.

Referring by letter to the drawings, A designates a ring, and A is theboxing to receive a stone or similar setting A The end walls of theboxing A are undercut, as at a, to provide keepers for the stone orsetting locking mechanism, which I will now describe.

B is a metal plate secured to the stone A It may be secured to the stonein any desired manner, and 1 do not limit myself to any specific meanstherefor; but I finditconvenient to provide the stone with alongitudinal groove having undercut side walls and to seat the plate Btherein, as plainly shown in Fig. 4. One end of the plate B is providedwith an integral locking lug or projection b to engage in one of thekeepers a, and the other end is provided with a rotary latch b, adaptedto engage in the other keeperaof the boxing. The latch bis of segmentalform, having a straight side b and is seated in a recess 12 in the plateB. A pivot a extends from the latch I) through a hole in the plate B andis provided with a transverse groove to receive a small screw-driver orsimilar tool for the purpose of turning the latch.

The bottom of the boxing is provided with a hole a through which thetool may be inserted to reach the pivot a.

I have shown the ring as provided with a hole a near each end of theboxing, as it is obvious that the stone may be turned with the latch toengage in either of the keepers a.

In inserting the stone the latch b is first turned so that its straightside 11 is outward and flush with the end of the plate B. Then theintegral lug b is inserted in one oil the keepers a. Then when the stoneis pushed down in place the latch 12 may be turned to project under theother keeper a. The looking position of the latch is plainly shown inFig. 7 of the drawings.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. In an article of jewelry, the combination, with the boxing, of thestone or setting, a log or project-ion thereon to engage in a keeper inthe boxing, and a rotary latch thereon to engage in another keeper inthe boxing, substantially as specified.

2. In an article of jewelry, the combination, with the boxing having thekeepers, of the stone or setting,the plate secured thereto having anintegral lug or projection to engage in one of the keepers, and therotary latch movable into the other of said keepers, substantially asspecified.

3. In an article of jewelry, the combination, with the boxing having thekeepers, of the stone or setting having the groove, the metal plateseated in said groove, an integral lug on said plate, and the rotarylatch seated in a recess in said plate, substantially as specified.

4. In an article of jewelry, the combination, with the boxing having thekeepers and a hole in its bottom, of the stone provided with a groovehaving undercut side Walls, a plate seated in the groove and engaged bythe side walls, an integral lug or projection on said plate to engage inone of the keepers, and a rotary latch on said plate having the pivotprovided with the transverse groove, substantially as specified.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 21st day of April, 1892.
